Hey guys!.. got another strange problem that I noticed today, I'm not sure if it's a problem or if it's normal but when I keep my foot on the break and I start the engine and I still keep my foot on the brake the car does a weird smooth like tumbling feel.. then I put it into drive and it's okay. I don't know if this is normal but it's done this once or twice to me but not always, after I put my car in drive, it doesn't do it anymore. Once in a while when I startup. can anybody maybe explain to me what this is? Again I have a 2011 Z4 30i
